What does a PERT chart visually represent?

A PERT chart, or Program Evaluation Review Technique chart, is designed specifically to visually represent the dependencies among various project tasks. It is a project management tool used to schedule, organize, and coordinate tasks within a project.

By illustrating the sequence of tasks and their interdependencies, a PERT chart helps project managers identify the critical path, which is the longest sequence of dependent tasks that determines the minimum completion time for the project. Understanding these dependencies is crucial for effective project planning and can help in optimizing resources and mitigating delays.

For instance, if Task B cannot start until Task A is completed, this relationship is clearly depicted in a PERT chart, highlighting the flow of the project activities. This focus on task interrelations allows teams to prioritize and allocate work efficiently.

While other options mention aspects relevant to project management, they do not accurately reflect the primary function of a PERT chart, which is centered on the visualization of task dependencies.
